The metainformation contained 44 * in the HTTP headers in response to a HEAD request SHOULD be identical 45 * to the information sent in response to a GET request. This method can 46 * be used for obtaining metainformation about the entity implied by the 47 * request without transferring the entity-body itself. This method is 48 * often used for testing hypertext links for validity, accessibility, 49 * and recent modification. 50 * </blockquote> 51 * </p> 52 * 53 * @version $Revision: 664505 $ 54 * 55 * @since 4.0 56 * 57 * @deprecated Please use {@link java.net.URL#openConnection} instead. 58 * Please visit <a href="http://android-developers.blogspot.com/2011/09/androids-http-clients.html">this webpage</a> 59 * for further details. 60 */ 61 @Deprecated 62 public class HttpHead extends HttpRequestBase { 63 64 public final static String METHOD_NAME = "HEAD"; 65 HttpHead()66 public HttpHead() { 67 super(); 68 } 69 HttpHead(final URI uri)70 public HttpHead(final URI uri) { 71 super(); 72 setURI(uri); 73 } 74 75 /** 76 * @throws IllegalArgumentException if the uri is invalid. 77 */ HttpHead(final String uri)78 public HttpHead(final String uri) { 79 super(); 80 setURI(URI.create(uri)); 81 } 82 83 @Override getMethod()84 public String getMethod() { 85 return METHOD_NAME; 86 } 87 88 } 89
